Abstract (en)

A motor control device detects acceleration of an object driven by a motor through a transmission mechanism, determines a correction command based on the detected acceleration of the driven object, corrects an operation command for the motor by the correction command thus determined, and then controls the motor operation based on the corrected operation command. In the process, a phase shifter combines an operation command signal indicating the operation command with a correction command signal indicating the correction command after adjustably changing the phase of the correction command signal with respect to the vibration of the driven object generated due to the natural vibration of the transmission mechanism.
